The crackles and pops do not happen in Moog Modular V, Arp2600V, ProphetV, or other plugins. They also happen regardless of CPU load.

Interestingly enough, if I moved the sliders using the mouse on the GUI.... The crackles do not happen. They only seem to happen when i use a Modulation Wheel to control Filter Cutoff or my Behringer BCR2000 to adjust pitch, Envelope Attack, Decay, etc values.

Found a solution to the crackling issue, in case anyone else is experiencing it:

Turn Video Hardware Acceleration down.

It's a pretty common fix for sound artifacts, but I haven't had a problem till now. Hope this helps someone else having the same problem.

I'm having the same problem with all of my Arturia products. I'll give your solution a shot when I get home. I haven't had to lower acceleration in many years and didn't think of that as a solution. Thanks for posting!
